Re: Pure Stock Drag Racing tips & tricks
 

Sam;
Explain that a little more? Are you saying that a solid lifter engine requires a blowproof? If that's the case, I'm SOL - I don't want to change the bell just for a few joy runs!

Re: Pure Stock Drag Racing tips & tricks
 

Anytime that I ran my car with solid lifters, I needed a Lakewood bellhousing. Maybe on there Friday nite grudge runs, or if their rules at the Grove changed, you will not need it. I think they are worried about your legs at high revs. Maybe it is time to make this a day 2 car!!!??? Remember NONE of these cars stayed really stock for more than a few weeks. It was almost impossible to keep these cars with the small tires, no traction bars, and no headers for any lenght of time. There was just way to much potential left in them. You could call Maple Grove and ask. A bellhousing is not really hard to do. Sam

Re: Pure Stock Drag Racing tips & tricks
 

I don't think a steel bellhousing is required until you get pretty quick. Here's the biggies you need to be concerned with:

- driveshaft loop = 13.99 (NHRA)
- helmet = 13.99 (NHRA)
- roll bar = 11.99 (NHRA) 11.50 (IHRA)
- 16 oz. catch can (NHRA)

I think you're supposed to wear long pants, and there may be some other little stuff I'm missing. Some of you other racers jump in here...

Correct me if I'm wrong ............
 

......but I DO believe that a Gobi Beige Deuce is LEGAL at the Pure Stock races ???? No ?????


I may have to with-hold my driveshaft loop retro knowledge until Marlin says he's bringin' the Deuce to the Pure Stocks .................. [img]/ubbthreads/images/icons/grin.gif[/img]

What's the problem ??? A PURE STOCK DEUCE is afraid of a lil 'ole W-31 Oldsmobile ?? We all know Olds' are sissy cars ............ [img]/ubbthreads/images/icons/grin.gif[/img]

Pure stock Deuce might be afraid, but not no Canadian COPO [img]/ubbthreads/images/icons/tongue.gif[/img] Casey....never kick a sleeping dog!

Peter - HUSH !!!!

I'm trying to get Marlin to bring out some of his iron. < Even tho it is Gobi Beige ...... > [img]/ubbthreads/images/icons/wink.gif[/img]

Re: Correct me if I'm wrong ............
 

Hey now! I would never pick on the sissy cars!

I will call the Grove to see what their rules are, still planning on making a spring time run - regardless of Casey's thoughts [img]/ubbthreads/images/icons/grin.gif[/img]

Re: Correct me if I'm wrong ............
 

Somebody explain the mechanics of wheel-hop, primarilary the pinion gear riding up on the ring gear. pxtx explained it to me in an email, seems logical, but how do spring clamps prevent wheel-hop and thereby increase traction. Will the spring clamps make the car rise rather than squat?

Sam,
Can't be making my car into a day 2 car! I would like to make it to the pure stock events in OH or MI one of these years.
Still learning,
Thx

Re: Correct me if I'm wrong ............
 

Marlin, this is a quote off another BB site and is a general description of wheel hop. Hopefully this gives you a little better understanding.

"Pinion angle is possibilty. I would shoot for a couple degrees down because once you get on the power, axle wind-up will bring it back to zero. That will be a trial and error process. As far as taking leafs out, I think that will hurt more than help. What's happening is the axle "wraps up" and pulls the spring to the shape of an "S" until it can't twist anymore then violently unwraps. This loading and unloading bounces the tire off the ground. Sofening the spring will make this worse. The Super Stock drag racers in the 60's used things called "spring clamps" which were basically just two pieces of flat stock drilled and tapped and bolted together around the spring leaves to keep them from separating under load effectively stiffening the spring. You might get away with just doing the right rear kind of like preloading a car with an airbag. If you REALLY want to get over your head get a book called "Circle Track Suspension" by Forbes Aird from Motorbooks International. There's more there than you want to know."
